I was told by an experienced member in Irc, that there is a new 0day tracker out. It's supposed to be very private. Right now it's still in beta, but i heard that the speeds and pretimes are amazing.
They say it will be the best 0day tracker very soon. Meaning better than scc/sct/ftn.

ps.I have a request for this tracker in the Req section..If anyone has an invite please go check my req out. Thanks
